PISTON RING COMPRESSOR Filed Feb. 10, 1926 Inventor Attorney 1,605,990H. c. SEGELKEN Nov. 9, 1926.

t eatise HERBERT G. SEGELKEN, 0F PHOEINTICIA, NEW YORK.

PISTON-BING- COMIPBESSOR.

Application filed February This invention relates to piston-ringcompress'ors, and has for its primary object to provide such acompressor that may be applied to a particular ring within a groove ofthe piston and then released for permitting both hands of the mechanicto properly force the piston into the engine cylinders, the compressorautomatically maintaining the ring in compressed condition after thesame has been once applied.

A further object resides in the provision of such a compressor that maybe easily applied to piston rings of various sizes and that may be usedfor the purpose intended without requiring any unusual skill upon thepart of the mechanic.

A. still further object is the provision of a compressor of the typementioned that is relatively simple in construction and inexpensive ofmanufacture, the invention comprising but few parts and these socorrelated as to reduce the possibility of the disarrangeinent to aminimum.

With the foregoing and other objects in view as the nature of theinvention will be better understood, the same comprises the novel form,combination, and arrangement of parts hereinafter more fully described,shown in the accompanying drawing, and claimed.

In the drawing wherein like reference characters indicate correspondingparts throughout both of the views:

1 is a longitudinal section of a piston-ring compressor constructed inaccordance with the present invention, and

Fig. 2 is a side elevation thereof.

Now having particular reference to the drawing, my novel piston ringcompressor includes a cylindrical handle member 5 of wood or othersubstantial but inexpensive material open at one end and provided at itsopposite closed end with a slot 6, the end walls of which are beveled asclearly shown in Fig. 1. The compressor further includes a relativelywide split spring steel ring 7 upon the ends of which are formed arms 8of spring steel that converge inwardly toward each other as clearlyshown in Fig. 1, the same adapted to enter the slot 6 of the cylindricalhandle 5, and from the ends of which arms extend relatively elongatedhorizontal bars 9 movable within the cylinder 5, the outer ends thereofextending outwardly of the cylinder and being so bent as to provideoutwardly extending finger Serial No. 87,328.

pieces 10 teat will engage the adjacent end of the cylinder for pi.venting the withdrawal of the bars therefrom. V

Surrounding said bars 9 between the tinger pieces 10 and the forward endof the cylinder 5 is an expans ble coil spring 11 that normally servesto draw the fingers 8 into the cylinder for consequently compressing theband 7, it being obvious that by forcing the bars 9 upwardly oroutwardly of the cylinder through the medium of the finpieces 10 theband 7 will by reason of the material forming the same expand forpermitting a piston ring A. to be disposed therein.

It will be obvious that after the band 7 has been applied to a pistonring within a piston groove and then released, the spring 11 willautomatically draw the bars 9 clownwardly within the cylinder, whichaction will move the arms 8 toward each other, consequently compressingthe band upon the ring and in turn compressing the ring within thegroove and flush with the piston wall for permitting the piston to bemoved down wardly within the engine cylinder, the positioning of thepiston within the cylinder being performed by both hands of the mechanicby reason of the fact that the com pressor will be automaticallymaintained in proper position.

Minor changes may be made in the invention without departing from thespirit and scope of the appended claims.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent is 1. In a compressor for piston rings, acylindrical handle member, a split spring steel band, rods upon the endsof the band slidable within said handle member, cooper atingconstruction between the rods and said handle member for normally movingthe band toward the handle and simultaneously compressing said band, andmeans at the opposite end of the handle whereby the band may be movedaway from the handle and into expanded condition.

2. In a compressor for piston rings, a normally expanded split steelband, a cylindrical handle member, rods extending from the ends of theband and entering said handle member, cooperating construction betweenthe rods and said handle member for drawing the rods through the handlemember and Simultaneously compressing iii-ii the band, and means at theopposite end of the rods externally of the handle Whereby the same maybe moved in a reverse direction to permit of the expansion of said band.

3. In a compressor for piston rings, a normally expanded split steelband, a cylindrical handle member, rods extending from the ends of theband through said handle,

the free ends of said rods being disposed laterally in oppositedirections to provide finger pieces for drawing' the rods through thehandle member and simultaneously cor pressing the band, and anexpansible coil spring arranged Within the handle and encircling saidrods.

In testimony whereof I aiiix my signature.
